Problem summary:
Out of the box, a USB 3.0 SATA 6.0 enclosure, hangs during reads or
writes and spits out some errors, when directly connected to a
computer's USB port. When connected via a USB hub, uas is still used,
but the errors do not occur. When setting a quirk to blacklist the
drive from uas, the problem doesn't happen when directly connected
either.

Start a copy (cp) with this volume as the source for reading, works
for a short while at normal speeds, but then within a few seconds,
throughput stops entirely per iotop, and only one kernel message:
[63246.094062] xhci_hcd 0000:00:14.0: ERROR Unknown event condition 10
for slot 6 ep 6 , HC probably busted
During this gap the access LED on the enclosure is flashing but
there's no throughput for the copy, and no user space or kernel
errors. I cancel the copy and then the following is found in dmesg:

If I use a quirk to disable uas for this drive, the problem doesn't happen.
/etc/modprobe.d/ignore_uas.conf containing the line:
options usb-storage quirks=152d:0567:u
And without the quirk the problem also doesn't happen if the drive is
connected to a powered USB hub.
This enclosure works out of the box without problems on Windows 10 on
the same hardware, as well as on a Mac.
Thanks,
